Cursed swords that bring bad fortune to whoever wields them. Or are they?

In the vast Sun-Ocean lies spots of perfect green. The Ankorillian Islands. The 'Jewels of the Blue'.
The natives there are strange and wild looking.
Here is the only existing work on how they live, their customs, beliefs and rituals.

Deep in the Ankorillian jungles grows the Corpse Flower. A dreaded plant that can entangle and poison you silently.
Hours later your companions notice your absence,
turn and search for you.
As they backtrack they unknowingly pass your last resting place.
A rather smelly, orange plant.

Within this ancient tome are 30 companion spirits for wizards and their ilk.

It is extremely cold and snow cover the plains as the heroes notice the dead frozen people hanging from the branches of scattered trees along the road. Ahead they see the local Lords soldiers hanging them up, mercilessly throwing buckets of water on their naked unprotected bodies until they freeze.

30 villages ready at the disposal of the Gamemaster.
